关于冬天的动物的英语美文篇一

Hibernation

Hibernation is more than sleep. It is a very deep sleep. The animal's temperature drops to just over zero centigrade, and its heart beats very slowly. People who find hibernating animals asleep often think that they are dead: the body feels very cold, and the creature may breathe only once every five minutes. A hibernating animal cannot feel any pain. You can touch it, or even pull its tail, without causing it to move or wake up. In its hibernating state it can even live in a poisonous atmosphere for a long time without any ill effect.

Hibernating in this way, the animal can sleep all through the winter. You might wonder how it manages to live without eating for so many months. The answer lies in two facts. The first is that it has stored supplies of fat in its body during the summer and autumn. The second is connected with the main use the body makes or rood——to supply the energy for movement. We have seen that hibernating animal reduces movement to far below the ordinary level. Even the movements or the heart and lungs are greatly reduced. The animal hardly makes any movement, hardly use any energy, and hardly needs any rood.

Some animals, including some bears only hair hibernate. That is to say, they sleep during the winter, but their sleep is not deep and their body temperature does not drop, as they are warm blooded animals. In the antumn the bear eats and eats and becomes very rat. His hair grows longer. Soon he has a thick covering or rat and fur. In November he rinds a place to lie down and goes to sleep. On warm winter days he may think spring has arrived;he gets up and wa[ks around. When he sees that the snow is still thick on the ground, he quickly goes to sleep again.

冬眠不仅仅是睡眠，而是一种沉睡。动物的体温降到刚好在零摄氏度以上，心脏跳动非常缓慢。人们看到处于冬眠状态的动物，常常以为它们是死的：身体摸上去冰凉，可能每5分钟才呼吸一次。冬眠的动物感觉不到任何疼痛。你可以摸它，拉它的尾巴，也不能使它动一动或醒过来。当它处于冬眠状态时，甚至可以长时间地生活在有毒空气中而无任何不良后果。

用这样的方式越冬，动物可以睡过整个冬天。你或许会觉得奇怪，它好几个月不吃东西，怎么活过来的呢?可以从两方面的事实中得到答案。第一，在夏秋季节，动物体内储存大量的脂肪。第一是与食物对身体的主要用途，即食物供给身体活动所需的能量有关。我们已经知道，冬眠的动物把活动量减少到大大低于一般的水平。甚至心肺的活动量也大大减少了。冬眠的动物几乎没有什么活动，几乎也不消耗什么能量。因此它也几乎不需要什么食物。

有些动物，包括有些熊，只是半冬眠。就是说，每到冬天它就睡觉，不过他们睡得不那么沉，因为他们属温血运动，所以体温不下降。在秋天，熊吃了又吃长得真是肥极了。它身上的毛也长得更长了，很快全身就包满了一层厚厚的脂肪和毛。到了11月，它找个地方躺下睡觉了。在冬天暖和的日子里，它可能以为春天已经来到了，便起来四处走走，当它看到地上积雪仍然很厚时，它很快又去睡了。

American researchers spent two summers studying polar bears on the Arctic sea ice. They found that sea ice, where polar bears spend much of their lives, is melting faster than experts predicted it would. The researchers say this change in the animals' home territory is threatening their survival.

美国科研人员用了两个夏天研究生活在北极海冰上的北极熊。他们发现，海冰正在快速地融化，比专家预测的还要快，而北极熊一生中的大部分时间都是在海冰上度过的。科研人员说，发生在北极熊家园领域内的变化正在威胁着它们的生存。

The scientists published a report on their study in the journal Science. The report says polar bears face a difficult future unless countries reduce air pollution.

这些科学家在《科学》杂志上发表了一篇跟他们的研究相关的报告，该报告声称，除非各个国家减少空气污染，否则北极熊的未来会非常严峻。

Polar bears live on the ice. It is where they hunt, mate and raise their young. But a team of researchers has found that the animals' ice habitat is warming up, and shrinking.

北极熊生活在海冰上。他们猎食、交配、生儿育女，处处离不开海冰。但是，一个科研团队已经发现，北极熊的海冰栖息地正在变暖和萎缩。

The team was from the University of Wyoming. Its members worked in the Arctic between 2008 and 2010. Merav Ben David was among the researchers. She says they learned that polar bears often have trouble finding food. She says the lack of food can affect their mental health.

这个科研团队来自怀俄明大学，团队成员在2008年到2010年之间对北极进行了研究。梅-本-傣威是成员之一。她说他们发现了北极熊常常在寻找食物上陷入困境，而缺乏食物会影响他们的心理健康。

"So if shortening of the spring hunting season, lengthening of the summer season where they are food-deprived and still experiencing difficulties in getting food in the winter, polar bears are stressed physiologically."

“因此，如果用于猎食的春季正在变短，而食物短缺的夏季正在变得漫长，冬季寻找食物又面临困难，北极熊的身体就会无法忍受。

Ms. Ben David says if the animals do not eat enough food in the spring, they are in poor health when winter arrives.

本-傣威女士说，如果这种动物春季进食不够充足，当冬天到来时，它们就会处在不健康的状态中。

The researchers traveled on helicopters and ships. They captured more than 20 polar bears, and tested their blood. Before releasing the animals, the researchers equipped them with devices to measure temperature. They then followed the movement of the polar bears on ice and on land.

科研人员的科研之旅是在直升机和轮船上度过的。他们捕捉了二十多头北极熊，检测了它们的血液。在它们身上安装了测量温度的设备后，他们释放了这些动物。接下来，他们对北极熊在海冰上和陆地上的行动轨迹进行了跟踪考察。

Other studies had suggested that the bears could deal with a lack of food in the summer by reducing their activity -- like the animals do when they hibernate in the winter. But Ms. Ben David says the researchers discovered that did not happen.

曾经有其他研究认为，通过减少活动，北极熊能够应对夏季食物的匮乏——就如同冬季冬眠一样。但是，本-傣威女士说，这种情况不会出现。

"We found that polar bears -- like their nearest relatives the brown bears -- are incapable of reducing their metabolic rate to the level that we see during winter hibernation. So there are limits on how long they can go without feeding in the summer."

“我们发现，类似于它们最近的近亲棕熊一样，北极熊是无法把它们的代谢率降低到我们所知的冬季冬眠时的标准的。所以，夏季没有食物，会影响北极熊到底能走多远。

Ms. Ben David says 20,000 to 25,000 polar bears live in the Arctic. She says the world should take action to protect them.

本-傣威女士疾呼，现在的北极，只有两万到两万五千头北极熊，为了保护它们，全世界都应展开行动。

"If we want to be responsible citizens of this planet, we have to do everything in our power to stop, reverse the trend of sea ice loss."

“如果我们想成为这个星球上勇于担责的公民，我们必须采取一切措施阻止、改变海冰减少的趋势。

She says countries must work to limit the greenhouse gases that studies have linked to rising temperatures. She says if that does not happen, polar bears could one day disappear from our planet.

她说，所有国家都必须投入到限制温室气体排放的工作中来，因为温室气体会引起气候变暖，如果不这样做，北极熊迟早会从地球上消失。

I have a cute little parrot, it wears a pale "sweater", and with the pinch of grey feathers, like a crown on it a little head, on the opposite side of the head has two black eyes, always in loud gurgling, small eyes following is red face, as if a shy of the beautiful princess, its mouth is gray, lovely and beautiful, not only can eat can sing, small mouth or climbing up and down the secret weapon! .

我有一只可爱的小鹦鹉，它穿着一件灰白色的“毛衣”，头上有撮灰黄色的翎毛，像一个皇冠一样戴在它小小的头上，头的两边有两个黑豆一般的眼睛，老是在咕噜咕噜的转着，小眼睛下面是红彤彤的小脸，仿佛是一位羞涩的美丽的公主，它的小嘴也是灰色的，又可爱又漂亮，不但能吃能唱，小嘴还是它爬上爬下的秘密武器呢!。

它是一个“舞蹈家”，我每天带它去练弹钢琴，每次它一听到“顺心”的，就开始“鹦鹉大开屏”——不停的展开双翅跳来跳去的，不信，你听我说，这天我带它去听我练钢琴我一弹起《听妈妈讲那过去的事情》，它就把低下呆呆地站在那儿一动不动，当我弹起《童年回忆》时它展开双翅抖动着，跳来跳去的像一位翩翩起舞的少女。

它也是一个“小馋嘴”虽然它的食盆里永远没空过，可每次我拿生菜叶子喂它时，它总是头也不抬一下的狂吃，不到两分钟美丽的生菜叶子立刻变成一把“破扇子”。
